| 摘 要： | 桑褐斑病菌容易在人工培养基上生长，其生长温度范围为８～３１℃，最适生长温度为２５℃左右；分生孢子需在水滴中发芽，２４℃经２４ｈ能全部发芽；病程主配温度有关，该菌能以分生孢子（厚垣孢子）形态越冬，成为第二年初次侵染的主要来源。

| Abstract: | A pathogen,Septogloeum mori Briosi et Cavara,which can cause a brown leaf spotdisease of mulberry tree grows easily on a artifical medium.The growth temperature ofthis fungus is at a range of 8-31℃ and its optimum growth temperature is about 25℃.The conidiospore could germinate only in weater drops and all germinated at 24℃ for24h.They were found that the disease process was mainly relative to temperature and the fungus could overwinter in the morphology of the chlamydospore,which could be-come the main and original cause of disease of the next year. |
